摘要

分析了联想分类的主要缺点。提出了一种新的不平衡数据分类方法。这是一种关联分类。不频繁的规则用于构建分类器规则集。该方法除了使用模式“X→Y”的置信度外，还使用模式“Y→X”的置信度。而且，训练时只保留稀有类的特征。实验结果表明，该方法具有良好的性能。

A Novel Approach to Classify Imbalanced Dataset Based on Rare Attributes and Double Confidences

The major weakness of associative classification is examined. A novel approach for classifying imbalanced dataset is proposed. It is an associative classification. Rules which are un-frequent are used to build the classifier rule set. Besides the confidence of pattern “X→Y”, the confidence of pattern “Y→X” is used in the approach. Further more, only features of rare classes are preserved while training. The good performance of the approach is shown by the experiments.
